Preparation of a naturally occurring D-erythro-(2S, 3R)-sphingosylphosphocholine using Shewanella alga NS-589.

Sphingosylphosphocholine, an N-deacylated derivative of sphingomyelin, has been found to be involved in many cellular events. This paper describes a new method for preparation of a D-erythro-sphingosylphosphocholine, which is naturally occurring but difficult to prepare by chemical methods, using marine bacteria as a biocatalyst. When cultured with Shewanella alga NS-589 in synthetic medium, sphingomyelin was found to be efficiently converted by sphingomyelin deacylase to sphingosylphosphocholine. Sphingosylphosphocholine was purified with a high yield from the culture supernatant and identified to be a D-erythro-(2S,3R)-isomer containing d18:1 sphingenine as a long-chain base by fast atom bombardment mass spectrometry and NMR analyses.[1]
